I am in a multiple monitor system so when firefox lost the focus the video disappear so i cannot use minvid very often.
It works for me even when Firefox is not in focus (like right now I am writing this post from Chromium and have minvid running a video simultaneously )
Can you check the scenario in one monitor mode but with focus on something else than FF?
it is was happening also to me but now if Firefox lost the focus is working but I am using Firefox nightly.
I’ve noticed this too. Sometimes the mini vid stays in the foreground when firefox is not, but other times it doesn’t. I can’t figure out what the difference is.
